Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and the interstellar space beyond the Sun's heliosphere. It was launched 16 days after its twin, Voyager 2. It communicates through the NASA Deep Space Network (DSN) to receive routine commands and to transmit data to ...

Of the 10 science instruments Voyager 1 started its journey with, four are currently gathering data on its cosmic environment, and each year, the spacecraft loses more of its precious power supply.
Given Voyager 1’s immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.
The spacecraft is currently about 15 billion miles (24 billion kilometers) away from Earth, while its sister vehicle, Voyager 2, has traveled more than 12 billion miles (20 billion kilometers ...
Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which was known to be quite large and to possess a dense atmosphere. This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. [22]
A Titan/Centaur-6 launch vehicle carries NASA's Voyager 1 at the Kennedy Space Center on Sept. 5, 1977. (NASA) The team eventually determined that the issue stemmed from one of the spacecraft’s ...
